The definition of restoring force
What is... Restoring Force- the force that acts to bring a body to its equilibrium position
The equation for frequency
What is... f=1/T
Which force is typically the restoring force in simple harmonic motion
What is... gravity
An object oscillating on a pendulum or spring will have zero acceleration at what point
What is... the equilibrium position
The factor or factors that affect the period of a pendulum
What is... the length L
The definition of equilibrium
What is... Equilibrium- the central position where the maximum displacement on one side is equal to the maximum displacement on the other side
The equation for Hooke's Law
What is... F=-kx
Where is the restoring force always directed?
What is... toward equilibrium
An object oscillating on a pendulum or spring will have zero velocity at what point
What is... maximum displacement
The factor or factors that affect the period of a spring
What are... the mass m and the spring constant k
The definition of the period of oscillation and frequency
What is... Period- the time it takes for one oscillation or cycle
frequency- the number of oscillations or cycles per unit time(measured in Hertz)
The equation for the period of a pendulum and for the period of a spring
What is... T=2(pi)square root of (L/g)
and T=2(pi) square root of (m/k)
Why is the restoring force a negative value?
It is the force that returns an object back toward its equilibrium position. It is directed opposite to the displacement so restoring force is negative
An object oscillating on a pendulum or spring will have maximum acceleration at what point
What is... maximum displacement
Does pushing a pendulum in oscillatory motion affect the pendulum's period?
No, the acceleration of the bob on the pendulum may change, but it remains proportional to its displacement as it swings. The applied force therefore has no affect on the period.
The definition of amplitude
What is... Amplitude- the maximum displacement of an oscillation from its equilibrium position
The equation for Potential spring energy
What is... Uspring=1/2kx2
What is Hooke's Law?( Not the equation)
The amount that the spring extends or compresses by some distance is proportional to the amount of force with which it pulls
An object oscillating on a pendulum or spring will have maximum velocity at what point
What is... the equilibrium position
Find the period of a pendulum located on earth that has a length of 5m and a bob with a mass of 3kg? Include units.
4.44 seconds
The definition of simple harmonic motion
What is... SHM- When an object is in oscillatory motion as a result of a restoring force acting toward equilibrium in which it travels an equal displacement back and forth from its equilibrium position
The equation for the restoring force(the component of gravity in direction of equilibrium)
What is... F=mgsin(theta)
If a pendulum is pulled back at an angle of 10 degrees with a mass of 1.5kg, what is the magnitude of the restoring force on the pendulum?
What is... F= 2.6 N
At what point does a pendulum or spring have maximum restoring force? What about zero restoring force?
What is... maximum displacement
What is.... the equilibrium position
The internal energy of a system includes the _____energy of the objects that make up the system and the ______ energy of the configuration of the objects that make up the system
What is... Kenetic Energy
Potential Energy
